Ruger 10/22 - How to Modify Bolt Release into an Automatic Bolt Release

I dont think you have to have it but it works best, use whatever you can fit in that small hole that will grind

do i have to have the diamond tipped dremil thing?

Did this last night on a brand new 10/22. works great.

I finished polishing the trigger assembly and hammer and seer and I feel reduced the trigger pull by about 1/3. My son says it feels more like half. I have two 10/22 and only polished the one so we could compare them. I don't have a scale to confirm the actual poundage reduction though. The trigger feels noticeable smoother in its movement. I am going to next get some thin washers and put them between the various assemblies to take out the lateral movement.

Unfortunately I don't know exactly how to make the trigger pull better, I haven't done any tinkering since I did this mod but from what I've read online it seems you have to rub all the contact parts of the sear and hammer with a wet stone, if you figure it out let me know because pulling the trigger on the 10/22 is more like pressing a button down on an old blender
